Part of the Fast Forward series, Nicholas Harris's Volcano zeroes in on one specific eruption, Italy's Mt. Vesuvius. Peter Dennis's richly detailed illustrations depict the devastation of the ancient Roman city of Pompeii. Tabs along the side provide a time line from the ice age to the present. Zoom ahead as tourists flock to the newly uncovered Pompeii, whose landmarks provide a comparative reference point throughout. Other Fast Forward titles: Castle; Shipwreck; and The Wild West. (Sept.)
